Whatever way you go, just remember, it is like anything else in this world. You get what you pay for.
My research has led me to consider "eheim substrat pro" or "seachem matrix". I decided to give matrix a try and am currently in the process of cycling it into my filtration "infrastructure". Prior to this, I have used eheim substrat (the original, not the pro) for the last 11 years. The original eheim substrat proved to be an awesome biological filtration media. I am moving to matrix, however, because I need to (at least attempt) address "nitrates". I am also using purigen, along with the matrix.
X2 on the ehiem stuff..i have also used these with good success in my other tanks.
